Abstract
An electromagnetic actuator for operating a cylinder valve in an internal combustion engine includes first and second housings secured to one another. Each housing has a cavity and a through bore extending therefrom. First and second electromagnets are disposed in the cavity of the respective housings. Each electromagnet has a yoke, a coil and a pole face. The pole faces are oriented toward and spaced from one another, and a reciprocating armature is disposed between the pole faces. A spring which urges the armature away from the first electromagnet has an end oriented away from the armature. A support cap is axially insertable in the through bore of the first electromagnet and includes a cap base having an inner face supporting the spring end. A locking arrangement secures the support cap to the housing and has a component axially insertable in the through bore with the support cap.
